Beethoven's Symphony No. 9 is a monumental piece of music composed between 1822 and 1824 and is widely regarded as one of his greatest works. It features four movements; a dramatic opening Allegro ma non troppo with a driving rhythm and memorable melodies. A blissful slow movement Adagio molto e cantabile with rich romantic textures, the mid-section Scherzo Allegro with its playful character, and finally the thrilling finale of the choral Ode to Joy with its joyful and optimistic fanfare.
